[Devel] [PATCH vz10 v3 06/11] ext4: remove inode_lock from ext4_sync_files

[Konstantin Khorenko]

From: Pavel Tikhomirov <ptikhomirov at virtuozzo.com>

Remove inode_lock_shared() and inode_unlock_shared() calls as they are
not needed for accessing inode information in this context.

Similar to upstream commit:
92e6222dfb85 ("ext4: remove i_mutex from ext4_file_sync()")

Part of rework for ext4_sync_files function.

Fixes: 26337aacaafa9 ("ext4: add mfsync support")
https://virtuozzo.atlassian.net/browse/VSTOR-107255
Signed-off-by: Pavel Tikhomirov <ptikhomirov at virtuozzo.com>

Feature: ext4: optimized sync of a set of files - mfsync()
